INTRODUCTION

Mental health problems, which may also be referred to as mental illness or psychiatric disorder, are behavioral or mental patterns which impair the functioning of individuals across the world. Psilocybin has been increasingly evaluated for treating mental health problems. Such mental health disorders include: personality disorders, anxiety disorders, major depressions, and various addictions. In contrast to anxiolytic medicines, usage of psilocybin does not lead to physical dependence.

DETAILED DESCRIPTION Abbreviations and Definitions

To facilitate understanding of the invention, a number of terms and abbreviations as used herein are defined below as follows:

Amino acids: As used herein, the term “amino acids” refer to the molecular basis for constructing and assembling proteins, such as enzymes. (See FIG. 1 for a table of amino acids.). Peptide bonds (i.e., polypeptides) are formed between amino acids and assemble three-dimensionally (3-D). The 3-D assembly can influence the properties, function, and conformational dynamics of the protein. Within biological systems, the protein may: (i) catalyze reactions as enzymes; (ii) transport vesicles, molecules, and other entities within cells as transporter entities; (iii) provide structure to cells and organisms as protein filaments; (iv) replicate deoxyribonucleic acid (DNA); and (v) coordinate actions of cells as cell signalers.

Nucleotides: As used herein, the term “nucleotides” refers to the molecular basis for constructing and assembling nucleic acids, such as DNA and ribonucleic acid (RNA). There are two types of nucleotides—purines and pyrimidines. The specific purines are adenine (A) and guanine (G). The specific pyrimidines are cytosine (C), uracil (U), and thymine (T). T is found in DNA, whereas U is found in RNA. The genetic code defines the sequence of nucleotide triplets (i.e., codons) for specifying which amino acids are added during protein synthesis.

Genes: As used herein, the term “genes” refers to regions of DNA. Amino acid sequences in the proteins, as defined by the sequence of a gene, are encoded in the genetic code.

The present invention is directed to biosynthetic production of psilocybin and related intermediates in recombinant organisms. The syntheses of psilocybin and intermediates of psilocybin in a laboratory environment typically involve tedious techniques of organic chemistry. Often reproducibility is elusive and the solvents used during the syntheses of psilocybin and intermediates of psilocybin are environmentally toxic. Decarboxylations, selective methylations, and selective phosphorylations can be difficult to obtain via the techniques of organic chemistry. Further, the yields and purity of the intermediates for obtaining the target molecules can be low using the techniques of organic chemistry, where the starting molecule is L-tryptophan and the target molecule is psilocybin.

The systems and method herein disclose more environmentally benign processes which can have higher throughputs (i.e., more robust processes). The systems and methods herein include: (i) growing modified recombinant host cells and thereby yielding a recombinant host organism; (ii) expressing engineered psilocybin biosynthesis genes and enzymes in the recombinant host organism; (iii) producing or synthesizing psilocybin and/or intermediates of psilocybin in the recombinant host organism; (iv) fermenting the recombinant host organism; and (v) isolating the psilocybin and/or intermediates of psilocybin from the recombinant host organism. Endogenous pathways of the recombinant host can be modified by the systems and methods herein to produce high purity psilocybin and/or intermediates of psilocybin.

Reference is made to the figures to further describe the systems and methods disclosed herein.

Referring to FIG. 2 , a table lists the enzymes involved in the direct biosynthesis of psilocybin and psilocybin intermediates in species of fungus (i.e., mushrooms). Gene source organisms provide a genetic starting source (i.e., raw gene sequences) which is codon optimized and engineered to function in the recombinant host organisms. The recombinant host organisms include but are not limited to: Schizosaccharomyces cerevisiae, Schizosaccharomyces japonicus, Schizosaccharomyces pombe, Schizosaccharomyces cryophilus, Saccharomyces cerevisiae, Kluyveromyces lactis, Kluyveromyces dobzhanskii, and Yarrowia lipolytica.

Further, the genes/enzymes that are inserted or engineered into the recombinant host are PsiD, PsiH, PsiK, and PsiM.

A PsiD enzyme, which is a decarboxylase (e.g., L-tryptophan decarboxylase) derives from a gene source organism herein—Psilocybe cubensis, Psilocybe cyanescens, and Gymnopilus junonius. The decarboxylase can catalyze the decarboxylation of an aliphatic carboxylic acid (i.e., release carbon dioxide) L-tryptophan to tryptamine and 4-hydroxy-L-tryptophan to 4-hydroxytryptamine, as depicted in FIG. 3 .

A PsiH enzyme, which is a monooxygenase (e.g., Tryptamine 4-monooxygenase) derives from a gene source organism herein—Psilocybe cubensis, Psilocybe cyanescens, and Gymnopilus junonius. The monooxygenase can catalyze the oxidative hydroxylation of the phenyl ring of tryptamine to 4-hydroxytryptamine, as depicted in FIG. 3 .

A PsiK enzyme, which is a kinase (e.g., 4-hydroxytryptamine kinase) derives from a gene source organism herein—Psilocybe cubensis and Psilocybe cyanescens. The kinase can catalyze the phosphorylation (i.e., adding O═P(OH)₂) of the phenolic oxygen of 4-hydroxytryptamine to norbaeocystin, as depicted in FIG. 3 . The kinase can also catalyze the phosphorylation of psilocin to psilocybin.

A PsiM enzyme, which is a methyl transferase (e.g., psilocybin synthase) derives from a gene source organism herein—Psilocybe cubensis, Psilocybe cyanescens, Panaeolus cynascens, Gymnopilus junonius, and Gymnopilus dilepis. The methyl transferase can catalyze the alkylation (i.e., adding a methyl (CH₃) group) of the primary amine in norbaeocystin to baecystin, as depicted in FIG. 3 . Another alkylation can take place where the methyl transferase when the secondary amine of baecystin becomes a tertiary amine of psilocybin, as depicted in FIG. 3 .

As depicted in FIG. 3 , the engineered PsiD, PsiH, PsiK, and PsiM enzymes act on substrates in the psilocybin biosynthetic pathway to produce intermediates of psilocybin and psilocybin itself. The initial substrate for psilocybin intermediates and psilocybin can be L-tryptophan and/or 4-hydroxy-L-tryptophan. These initial substrates can be produced endogenously in a recombinant host as described and/or provided exogenously to a fermentation involving a recombinant host, whereby the host uptakes the starting substrates to feed into the psilocybin biosynthetic pathway. The recombinant host herein described that is expressing all, one, or multiple combinations of the engineered PsiD, PsiH, PsiK, PsiM genes can produce tryptamine, 4-hydroxytryptamine, norbaeocystin, baeocystin, psilocybin, and psilocin. Psilocybin may be converted to psilocin due to spontaneous dephosphorylation. Psilocin is in turn an intermediate which can be acted on by the PsiK enzyme to produce psilocybin.

As depicted in FIG. 8 , the endogenous pathways of a recombinant host organism produce precursors for the engineered PsiD, PsiH, PsiK, PsiM genes. Pathways relating to chorismate, L-glutamine, and L-serine, feed into the endogenous pathway for L-tryptophan production, which a recombinant host organism expressing the psilocybin biosynthetic pathway herein described can use to create tryptamine, 4-hydroxytryptamine, norbaeocystin, baeocystin, psilocin, and psilocybin. The enzymes in the endogenous pathways of the recombinant host organism are encircled in FIG. 8 . Glycolysis and gluconeogenesis in combination with ARO3, ARO4, ARO1, and ARO2 enzymes can be subjected to the depicted precursors at the specified point in the pathway to selectively yield chrorismate. The glutamate biosynthesis pathway in combination with a GLN1 enzyme can be subjected to the depicted precursor at the specified point in the pathway to selectively yield L-glutamine. Glycolysis in combination with SER3, SER33, SER1, and SER2 enzymes can be subjected to the depicted precursors at the specified points in the pathway to selectively yield L-serine. Chorismate and L-glutamine in combination with TRP1, TRP2, TRP3, and TRP4 enzymes can be subjected to the depicted precursors at the specified point to selectively yield (1S,2R)-1-C-indol-3-yl)glycerol 3-phosphate. The addition of L-serine to (1S,2R)-1-C-indol-3-yl)glycerol 3-phosphate in the presence of the TRP1 enzyme can yield L-tryptophan.

As depicted in FIG. 9 , a scheme to increase metabolic flux through the shikimate-chorismate and L-tryptophan pathways is disclosed. The increased metabolic flux through the shikimate-chorismate and L-tryptophan pathways increases the production of L-tryptophan, a key precursor compound for the production of psilocybin and intermediates of psilocybin. Specific enzymes in the described native pathways are overexpressed. Enzymes subject to allosteric inhibition are mutated and overexpressed to render the enzymes insensitive to feedback mechanisms. Enzymes that consume pathway intermediates for off-pathway compound production are hereby deleted.

L-tryptophan production is improved herein by overexpressing a series of enzymes that first increase production of the aromatic compound intermediate, chorismate in a series of enzymatic reactions known as the shikimate pathway. As described in FIG. 5 , the shikimate-chorismate pathway initial precursors, PEP and E4P are converted into 3-deoxy-D-arabinoheptulosonate 7-phosphate (DAHP), catalyzed by ARO3 and ARO4 enzymes.

Overexpression of the genes encoding ARO3 enzyme (as encoded by codon optimized SEQ ID NO: 29), and a feedback-resistant mutant ARO4 K229L enzyme (as encoded by codon optimized SEQ ID NO: 30) are described herein and can increase metabolic flux through the pathway. In addition, genes that encode key enzymes, ARO1 enzyme (as encoded by codon optimized SEQ ID NO: 27) and ARO2 (as encoded by codon optimized SEQ ID NO: 28) are overexpressed as part of a series of enzymes that can convert DAHP to chorismate. In addition, the gene that encodes the Escherichia coli shikimate kinase II (AROL enzyme) can be overexpressed to increase pathway flux from DHAP to chorismate via codon optimized SEQ ID NO: 31.

Chorismate as a general precursor compound can be converted specifically to L-tryptophan by overexpressing a series of enzymes in the L-tryptophan pathway. As described in FIG. 9 , flux through the L-tryptophan pathway can be increased by overexpressing the genes that encode specific enzymes, TRP1 enzyme (as encoded by codon optimized by SEQ ID NO: 32), TRP3 enzyme (as encoded by codon optimized by SEQ ID NO: 34), and TRP4 enzyme (as encoded by codon optimized by SEQ ID NO: 35). Furthermore, overexpression of the gene that encodes the feedback-resistant mutant of TRP2 S76L enzyme (as encoded by SEQ ID NO: 33) is described herein.

Chorismate is a precursor that feeds into the metabolic pathways that produce a variety of aromatic alcohols and aromatic amino acids. The mechanism made operable by systems and methods herein reduce pathway flux into pathways that produce off-pathway targets. As described in FIG. 9 , genes that encode native enzymes—PDC5 enzyme and ARO10 enzyme—have been deleted to reduce pathway flux through the pathways that produce aromatic alcohols. The gene that encodes the native enzyme, ARO7 enzyme has been deleted to reduce production of tyrosine and phenylalanine. Genes that encode PDZ1 and PDZ2 enzymes have been deleted to reduce pathway flux through the pABA production pathway.

As depicted in FIG. 10 , a modified heterologous recombinant host organism is: (i) expressing endogenous pathways for L-tryptophan; (ii) expressing a recombinant version of the TAT2 L-tryptophan importer protein; and (iii) selectively expressing recombinant psilocybin biosynthetic pathway genes. Such a recombinant host can produce tryptamine, 4-hydroxytryptamine, norbaeocystin, baeocystin, psilocin, and psilocybin from L-tryptophan. L-tryptophan can be created by the host through endogenous pathways (FIG. 8 ) or engineered pathways (FIG. 9 ). L-tryptophan may also be fed to the recombinant host organism by media supplementation and up taken by the host expressing the recombinant TAT2 importer protein. Accordingly, contact with the L-tryptophan and the recombinant host organism in the media can selectively direct flux towards psilocybin. Other carbon sources can make contact with the recombinant host organism in the media, wherein the other carbon sources include at least one of: glucose, galactose, sucrose, corn steep liquor, ethanol, fructose, and molasses.

Besides the recombinant TAT2 importer protein, which is encoded by a codon optimized L-tryptophan importer (SEQ ID NO: 36), the nucleotide and amino acid sequences provided are in the order of the psilocybin pathway: PsiD, PsiH, PsiK, and PsiM genes which encode for the respective enzymes. In the systems and methods herein, PsiD enzyme selectively and cleanly catalyzes decarboxylation; the PsiH enzyme catalyzes selective hydroxylation at the 4-position of an indole; the PsiK enzyme catalyzes selective phosphorylation at the hydroxylated 4-position of an indole; and the PsiM enzyme catalyzes selective and stepwise methylations of an amine group, respectively.

By expressing the PsiD gene in the recombinant host organism, codon optimized nucleic acid sequences SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3 encode for isolated amino acid sequences SEQ ID NO: 14, SEQ ID NO: 15, and SEQ ID NO: 16, respectively. Using the techniques of organic chemistry, decarboxylations would require harsh and toxic tin hydrides (e.g., Barton Decarboxylation), as opposed to the selective and clean decarboxylation by the PsiD enzyme in the recombinant host.

By expressing the PsiH gene in the recombinant host organism, codon optimized nucleic acid sequences SEQ ID NO: 4, SEQ ID NO: 5, and SEQ ID NO: 6 encode for isolated amino acid sequences SEQ ID NO: 17, SEQ ID NO: 18, and SEQ ID NO: 19, respectively. Phenyl group functionalization is often done at high temperatures and pressures, while leading to a mixture of products (e.g., hydroxylations at the 5, 6, and 7 positions of the indole). The regioisomers of the hydroxylated products at the 5, 6, and 7 positions of the indole are structurally distinct from each other, but also structurally similar to each other. Separation of such regioisomers can be very challenging and requires cumbersome separation techniques (e.g., slow column chromatography with poor separation (i.e., the regiosiomers have similar R_(f) values to each other) and low accompanying yields). In contrast, the PsiH enzyme catalyzes selective hydroxylation of indole at the 4-position in the recombinant host organism herein at standard room conditions (˜25 degrees Celsius at ˜1 atm of atmospheric pressure). The systems and methods herein can produce and increase the titers of the hydroxylated indole at the 4-position within the recombinant organism. Using the purification techniques, as described in more detail with respect to the Examples, a sample can be obtained, which exclusively contains the hydroxylated indole at the 4-position. This is indicative of a more facile procedure for obtaining the hydroxylated indole at the 4-position, in comparison to the techniques of organic chemistry.

By expressing the PsiK gene in the recombinant host organism, codon optimized nucleic acid sequences SEQ ID NO: 7 and SEQ ID NO: 8 encode for isolated amino acid sequences SEQ ID NO: 20 and SEQ ID NO: 21, respectively. Primary amines and indole nitrogen are nucleophilic groups than can compete with phenolic oxygen for phosphorylation. In contrast, the recombinant host supports the PsiK enzyme catalysis of selective phosphorylation of the phenolic oxygen. The recombinant host and the PsiK enzyme can also catalyze the undoing of de-phosphorylations that yield psilocin. Stated another way, the recombinant host organism and the expressed PsiK gene for encoding the PsiK enzyme can convert psilocin back to the target molecule psilocybin. Stated yet another way, the recombinant host organism and the expressed PsiK gene for encoding the PsiK enzyme can provide a corrective mechanism to obtain the target molecule psilocybin.

By expressing the PsiM gene in the recombinant host organism, codon optimized nucleic acid sequences SEQ ID NO: 9, SEQ ID NO:10, SEQ ID NO:11, SEQ ID NO: 12, and SEQ ID NO: 13 encode for isolated amino acid sequences SEQ ID NO: 22, SEQ ID NO: 23, SEQ ID NO: 24, SEQ ID NO: 25, and SEQ ID NO: 26, respectively. The primary amine when subjected to methyl iodide may get over alkylated to the quaternary amine. Further, the reaction is not selective as monoalklyated and dialkylated products may also be obtained. To further complicate the alkylation, the nitrogen of the indole is sufficiently nucleophilic to perform alkylations. In contrast, the PsiM enzyme catalyzes selective methylation at the primary amine in the recombinant host organism, which is also stepwise. The first methylation yields norbaeocystin and the second methylation yields psilocybin. The indole nitrogen does not get methylated.

SEQ ID NO: 1-SEQ ID NO: 36 of the systems and methods herein aid in increasing titers of psilocybin in the recombinant host organism in comparison to the titers of psilocybin in natural state of the host organism. As described above, the mutations at specific points of the pathways above direct flux toward yielding psilocybin in the recombinant host organism.

In the examples below, genetically engineered host cells may be any species of yeast herein, including but not limited to any species of Saccharomyces, Candida, Schizosaccharomyces, Yarrowia, etc., which have been genetically altered to produce precursor molecules, intermediate molecules, and psilocybin molecules. Additionally, genetically engineered host cells may be any species of filamentous fungus, including but not limited to any species of Aspergillus, which have been genetically altered to produce precursor molecules, intermediate molecules, and psilocybin molecules. Some of the species of yeast herein for the recombinant host organism include but are not limited to: Schizosaccharomyces cerevisiae, Schizosaccharomyces japonicus, Schizosaccharomyces pombe, Schizosaccharomyces cryophilus, Saccharomyces cerevisiae, Kluyveromyces lactis, Kluyveromyces dobzhanskii, and Yarrowia lipolytica.

The gene sequences from gene source organisms are codon optimized to improve expression using techniques disclosed in U.S. patent application Ser. No. 15/719,430, filed Sep. 28, 2017, entitled “An Isolated Codon Optimized Nucleic Acid”. The gene source organisms can include, but are not limited to: Psilocybe cubensis, Psilocybe cyanescens, Panaeolus cynascens, Gymnopilus junonius, and Gymnopilus dilepis. DNA sequences are synthesized and cloned using techniques known in the art. Gene expression can be controlled by inducible or constitutive promoter systems using the appropriate expression vectors. Genes are transformed into an organism using standard yeast or fungus transformation methods to generate modified host strains (i.e., the recombinant host organism). The modified strains express genes for: (i) producing L-tryptophan and precursor molecules to L-tryptophan; (ii) increasing an output of L-tryptophan molecules and precursor molecules to L-tryptophan molecules; (iii) increasing the import of exogenous L-tryptophan into the host strain; and (iv) the genes for the psilocybin biosynthetic pathway. In the presence or absence of exogenous L-tryptophan, fermentations are run to determine if the cell will convert the L-tryptophan into psilocybin. The L-tryptophan and psilocybin pathway genes herein can be integrated into the genome of the cell or maintained as an episomal plasmid. Samples are: (i) prepared and extracted using a combination of fermentation, dissolution, and purification steps; and (ii) analyzed by HPLC for the presence of precursor molecules, intermediate molecules, and psilocybin molecules.

Using the systems and methods herein, the genes which can be expressed to encode for a corresponding enzyme or other type of proteins include but are not limited to: PsiM, PsiH, PsiD, PsiK, TRP1, TRP2 S76L, TRP3, TRP4, ARO1, ARO2, ARO3, ARO4 K229L, and AROL. For example, the PsiM gene is expressed or (overexpressed) to encode for the PsiM enzyme; the PsiH gene is overexpressed to encode for the PsiH enzyme; and so forth. These PsiM, PsiH, PsiD, and PsiK genes can derive from: Psilocybe cubensis, Psilocybe cyanescens, Panaeolus cynascens, Gymnopilus junonius, and Gymnopilus dilepis. These TRP1, TRP2 S76L, TRP3, TRP4, AR01, ARO2, ARO3, and ARO4 K229L genes can derive from Saccharomyces cerevisiae. These AROL genes can derive from Escherichia coli. Further, these genes are transformed into Schizosaccharomyces cerevisiae, Schizosaccharomyces japonicus, Schizosaccharomyces pombe, Schizosaccharomyces cryophilus, Saccharomyces cerevisiae, Kluyveromyces lactis, Kluyveromyces dobzhanskii, and Yarrowia lipolytica. The PsiM, PsiH, PsiD, PsiK, TRP1, TRP2 S76L, TRP3, TRP4, ARO1, ARO2, ARO3, ARO4 K229L, and AROL genes which derive from at least one of: Psilocybe cubensis, Psilocybe cyanescens, Panaeolus cynascens, Gymnopilus junonius, Gymnopilus dilepis, Saccharomyces cerevisiae, and Escherichia coli can be expressed at the same time. Gene sequences can be determined using the techniques disclosed in U.S. Nonprovisional patent application Ser. No. 16/558,909 filed on Sep. 3, 2019, entitled “Automated Pipeline”.

Example 1—Construction of Saccharomyces cerevisiae Platform Strains with Elevated Metabolic Flux Towards L-Tryptophan Via Overexpression of the Feedback Resistant Mutant, ARO4 K229L

The optimized ARO4 K229L gene is synthesized using DNA synthesis techniques known in the art. The optimized gene can be cloned into vectors with the proper regulatory elements for gene expression (e.g. promoter, terminator) and the derived plasmid can be confirmed by DNA sequencing. As an alternative to expression from an episomal plasmid, the optimized ARO4 K229L gene is inserted into the recombinant host genome. Integration is achieved by a single cross-over insertion event of the plasmid. Strains with the integrated gene can be screened by rescue of auxotrophy and genome sequencing.

Example 2—Construction of Saccharomyces cerevisiae Platform Strains with Elevated Metabolic Flux Towards L-Tryptophan Via Deletion of PDC5

Deletion of PDC5 is performed by replacement of the PDC5 gene with the URA3 cassette in the recombinant host. The PDC5 URA3 knockout fragment, carrying the marker cassette, URA3, and homologous sequence to the targeted gene, PDC5, can be generated by bipartite PCR amplification. The PCR product is transformed into a recombinant host and transformants can be selected on synthetic URA drop-out media. Further verification of the modification in said strain can be carried out by genome sequencing, and analyzed by the techniques disclosed in U.S. Nonprovisional patent application Ser. No. 16/558,909 filed on Sep. 3, 2019, entitled “Automated Pipeline”.

Example 3—Method of Growth

Modified host cells that yield recombinant host cells, such as the psilocybin-producing strain herein, express engineered psilocybin biosynthesis genes and enzymes. More specifically, the psilocybin-producing strain herein is grown in rich culture media containing yeast extract, peptone and a carbon source of glucose, galactose, sucrose, fructose, corn syrup, corn steep liquor, ethanol, and/or molasses. The recombinant host cells are grown in either shake flasks or fed-batch bioreactors. Fermentation temperatures can range from 25 degrees Celsius to 37 degrees Celsius at a pH range from pH 4 to pH 7.5. Exogenous L-tryptophan can be added to media to supplement the precursor pool for psilocybin production, which can be up taken by strains expressing the TAT2 L-tryptophan importer protein. The strains herein can be harvested during a fermentation period ranging from 12 hours onward from the start of fermentation.

Example 4—Detection of Isolated Product

To identify fermentation derived psilocybin produced by a recombinant host expressing the engineered psilocybin biosynthetic pathway, an Agilent 1100 series liquid chromatography (LC) system equipped with a HILIC column (Obelisc N, SIELC, Wheeling, Ill. USA) is used. A gradient is used of mobile phase A (ultraviolet (UV) grade H₂O+0.1% Formic Acid) and mobile phase B (UV grade acetonitrile+0.1% Formic Acid). Column temperature is set at 40 degree Celsius. Compound absorbance is measured at 220 nanometers (nm) and 270 nm wavelength using a diode array detector (DAD) and spectral analysis from 200 nm to 400 nm wavelengths. A 0.1 milligram (mg)/milliliter (mL) analytical standard is made from psilocybin certified reference material (Cayman Chemical Company, USA). Each sample is prepared by diluting fermentation biomass from a recombinant host expressing the engineered psilocybin biosynthesis pathway 1:1 in 100% ethanol and filtered in 0.2 um nanofilter vials. Samples are compared to the psilocybin analytical standard retention time and UV-visible spectra for identification. As depicted in inset A of FIG. 11 , a fermentation derived product is obtained which has absorption of 300 au at 220 nm with a retention time of 4.55 minutes in a HPLC chromatogram. As depicted in inset B of FIG. 11 , the fermentation derived product obtained matches the retention time of the psilocybin analytical standard in the overlaid HPLC chromatograms. This indicates that the fermentation derived product is psilocybin. As depicted in inset C of FIG. 11 , the UV-visible spectra of the fermentation derived product and the psilocybin analytical standard are identical. This further corroborates that the fermentation derived product is psilocybin.
